In case you missed it, everyone down under was busy celebrating Australia Day on Sunday, and you may want to book your ticket for next year, because it looked like the most perfect of holidays. Marking the first arrival of British fleets in 1788, it's a fun, sunny holiday that honors the nation's beginnings. Based on the Instagram evidence, we should all be celebrating, Aussies or not. First of all, it involves beach days in January, and second of all, there are fireworks and giant parties and — once again — so much sun. As those in the northern hemisphere bundle up to stay warm, take a look at these wild photos from Australia Day, and start planning next year's trip now.
